You know Brian, that is a tough question. I'm with you that I would have been like, "Woo-Frickin-Hoo!", but I get the heeby-jeebies thinking about a guy teacher screwing a 16 year old student. If I was the Father I'd want to shoot him in the head.
So yeah, I think there is a double standard, but really, I have to come down on the side of it's really not right no matter wich gender's screwing wich.
